Abstract

POLIMEROS DE HIDROCARBUROS CON INJERTOS DE POLIETERES, POLILACTONES, O POLIESTERES DE LA REACCION DEL FOSGENO CON GLICOLES QUE TIENEN DE 1 A 4 ATOMOS DE CARBONO SE DESCUBRE QUE TIENEN BUENAS PROPIEDADES DE LIBERACION O BAJA ADHESION A MATERIALES DE CAUCHO DE HIDROCARBUROS. LOS POLIMEROS CON ELEMENTOS PRINCIPAL DE HIDROCARBUROS INCLUYEN EPDM, POLIBUTADIENO HIDROGENADO, Y POLI (ESTIRENO BUTADIENO) HIDROGENADO, TODOS LOS POLIMEROS CITADOS TIENEN GRUPOS ANHIDRIDO SUCCINICOS PENDIENTES O COPOLIMEROS DE ISOBUTILENO METILESTIRENO EROS ARRIBA REFERIDOS INJERTADOS CON CAUCHO DE ACRILONITRILO BUTADIENO O POLIMEROS EPICLOROHIDRINAS OCOPOLIMEROS SE HAN DESCUBIERTO COMO POLIMEROS UTILES PARA HACER CAPAS ENDURECIDAS DE AUTO LIBERACION O TUBULARES PARA EMPLEAR EN LA FABRICACION DE ARTICULOS MOLDEADOS TALES COMO CUBIERTAS DE NEUMATICOS.HYDROCARBON POLYMERS WITH GRAFTING OF POLYETHERS, POLYLACTONS, OR POLYESTERS FROM THE REACTION OF PHOSGEN WITH GLYCOLS THAT HAVE 1 TO 4 ATOMS OF CARBON, IT IS DISCOVERED THAT THEY HAVE GOOD PROPERTIES OF RELEASE OF MATERIALS AND LOW BONDING OF MATERIALS. POLYMERS WITH MAIN ELEMENTS hydrocarbons include EPDM, hydrogenated polybutadiene, and poly (styrene butadiene) HYDROGENATED, all polymers mentioned have anhydride groups succinic pending or isobutylene methylstyrene EROS UP REFERRAL grafted acrylonitrile butadiene or POLIMEROS epichlorohydrins OCOPOLIMEROS HAVE DISCOVERED AS USEFUL POLYMERS TO MAKE HARD COATS OF SELF-RELEASE OR TUBULAR FOR USE IN THE MANUFACTURE OF MOLDED ITEMS SUCH AS TIRE COVERS.
